Convergence of compact-surface beta-zero packing to the planar density

At least 9 years old · documented by

Let S\mathcal{S} be a compact Riemann surface, let U(z,w)U(z,w) be its logarithmic monopole, and for a positive real β\beta define

ρn,β(S)=inf⁡b,z1,…,zn1a(S)∫S(b eβU(⋅,z1)+⋯+βU(⋅,zn)−1)2 dAS,\rho_{n,\beta}(\mathcal{S})=\inf_{b,z_1,\ldots,z_n}\frac{1}{a(\mathcal{S})}\int_{\mathcal{S}}\big(b\,\mathrm{e}^{\beta U(\cdot,z_1)+\cdots+\beta U(\cdot,z_n)}-1\big)^2\,\mathrm{d} A_{\mathcal{S}},

where the infimum is over positive reals bb and points z1,…,zn∈Sz_1,\ldots,z_n\in\mathcal{S}. Compact-surface convergence conjecture. For any fixed compact surface S\mathcal{S} and any fixed positive real β\beta,

lim⁡n→+∞ρn,β(S)→ρβ(C).\lim_{n\to+\infty}\rho_{n,\beta}(\mathcal{S})\to\rho_\beta(\mathbb{C}).

The conjecture predicts that the limiting average discrepancy on every fixed compact surface agrees with the planar density; the source gives no resolution.
